Voice Privacy
When you activate your phone’s Voice Privacy feature, you 
request your cellular system to search for a Voice Privacy 
channel with each call. If no Voice Privacy channel is 
available (or your call is “handed off” to a cell where a Voice 
Privacy channel is not available), a series of short beeps 
alerts you that the call is no longer private.
You must select the Voice Privacy feature before you make a 
call in order for that call to search for a Voice Privacy 
channel.
Keep in Mind: This feature is not available in all markets. 
Contact your Service Provider for additional information 
about your service area.
